To all 1li/0m 'it may concern:

Be it known that l, GEORGE ldfnirnnrno, a citizen of the United States, residing at the city and county ot San Francisco and State oil? California, have invented certain new and useful Improvements in Pole-Base Constructions, oi whiclrthe following is a speciiication.

Poles or posts employed prin-iarily inthe supporting of wires, cables or other connecting means are preferably constructed of wood with their butts or bases inserted a short distance in the ground. The mounting of the poles in this manner has demonstrated that the action of the elements on the pole or post for a short distance both above and below the surface olil the soilsoon rots thc pole or post at this point, and the same having` become weakened often breaks at the ground under the weight oi the load supported.

My invention relates to the construction of a pole base, preferably prior to inserting the pole in the ground, whereby a preservative solution is contained within the heart of the pole base, and the pole surface, at a point for a short distance above and below the ground, is protected by an absorbent covn ering adapted to containv a preservative solution, which covering is in turn protected and the solution thus prevented from evaporating, and which second covering is in turn reinforced by a metallic wire structure.

With the above mentioned and other objects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construc tion within the scope of the claims may be resorted to without departing from the spirit or sacriiicing any ot' the advantages of the invention.

To more clearly comprehend the invention, reference is directed to the accompanying drawings, wherein i Fig. l is a view in elevation ot' a pole base or butt partly in broken section, illustrating the preferred embodiment of my invention.

Fig. 2 is a view in elevation of a pole illustrating the protected butt or base in full elevation.

ol lig. l, illustrating thethiinble reinforcing the central bore.

Referring more particularly to the draw ings wherein like characters ol reference designate corresponding parts-l indicates a channel or bore formed centrally ol: the butt or base of the pole 2 and the saine ei;- tends thereinto to a point preferably above the point 'ot insertion oil" the pole butt or,

base in the ground when the same in rise, The bore or channel is surrounded at the ei;-

treine lower end et the pole by a metallicv thimble 3 which forms a reinforcement surrounding the bore anni prevents the splittii'ig of the base oi the pole when the plug 4. to 1 iluid, permitting the seepage the-rect onti wardly through the wood bers.

The periphery of the pole base is preterably turned or annularly recessed as at 6 and within said recess is positioned a lilling `of absorbent 7, the outer layer of which eXi `tends beyond the upper and lower edges oi'f the recess 6; The absorbent is preferably felt, moss or the like, and the saine is saturated with any suitable preservative. Around this absorbent is positioned a wrapping of thin wood, either in the form ot staves 8 or a continuous veneer, Fig. l illustrating staves and Fig. 2 a `continuous veneer 8, and the same projects beyond the upper and lower edges ot the turned recess 6.

The wood protecting sheath is maintained in positionl and is protected from damage by the spiral wrapping or wire 9, one end of which is anchored as at l0 in the pole base and the remainder of which is tightly coiled spirally about the protecting sheath to a point near its upper end where the coils contact, forming a continuous wire surface 1l extending over and beyond the upperedge of the sheath 8, affording a means for shed ding' water which during storms may flow down the pole.

lf desirable, the channel o may be sup plied with a valve closure, not shown, and

the preservative fluid may be pumped therein under pressure and the valve closed.

It will be observed that the absorbent 7 saturated with the preservative prior to positioning Within the Channel (i, will retain the moisture, and thus protectthe surface oll the pole base `from the action of the elements.

By annularly recessing` the pole at 6, which recess extends above and below the surface of the ground into which the pole butt is insertedu remove the sott surtace of the pole, which is easily alieeted by 'the elements and rapidly decays.

My improved construction enables the seepage of the preservative 'fluid from the reservoir l outwardly through the pole to be caught by the absorbent 7 and thus maintain said absorbent saturatefil with the preservative tlnid, thus protecting` 'the surface `ot' the pole 'from decaying by the action oil' the elements.

Having thus described my .invention7 what l claim as new and desire to secure by Letters Patent of the United States is :c

l. ln combination with a pole provided with a longitudinal channel in its butt end forming a reservoir for containimb` a body of wood preservative tluid, said channel terminating at its upper end in a filling inlet opening at one side of the pole, a body oit absorbent 'lorl surrounding the pole butt within the length of said Channel, and means surrounding` said body of absorbent for proy testing the same and retaining it in position about 'the pole whereby the preservative seeping outwardly through the pole butt from said reservoir will maintain said absorbent moist. i
